Budding splits the colony
A repellent does not kill a multi-queen colony, it divides it. A queen and several hundred workers shift to a new site, leaving you with two nests instead of one.

Local technicians, fixed prices and a written report for every job in Pemulwuy.
Pemulwuy sits about 26.8 km west of the CBD in the Greater Parramatta & Cumberland, and postcode 2145 is one we are in most weeks. We cover Pemulwuy on scheduled runs through the Greater Parramatta & Cumberland, and we will give you a firm time rather than a window.
Our Pemulwuy work takes in the streets by Warmuli Reserve and Cumberland Country Golf Course, through to Marrong Reserve at the other end.
The suburb sits in the City of Parramatta and Cumberland area. Prospect, Greystanes and Pendle Hill are all covered on the same day, so a problem that has spread across a boundary can be handled in one visit. The building stock is close-packed, so we look at what the property adjoins before deciding where product goes.
Pemulwuy jobs tend to be apartments and converted blocks where the kitchen backs onto a service riser. Let us know which when you ring and we will plan the visit around it.
Every part of 2145 is covered as standard.
The 2145 run is set the day before and you are given an arrival time. Where Prospect and Greystanes fall on the same round, we can usually bring the visit forward.
Ants lay a pheromone trail that other workers follow, which is why the line is so precise and why it reappears in exactly the same place after you wipe it. Cleaning a Pemulwuy kitchen removes the smell for a few hours, not the colony that laid it.
Indoor nests sit in wall cavities, behind splashbacks, under baths and in roof insulation. Finding them is most of the work on a Pemulwuy job.
Ants will defend aphids and scale from predators because that honeydew is their sugar supply. Deal with the scale on the plants near the house and the ant pressure drops with it.
Each of these behaves differently, so the bait and the placement change too. Two photos come from our own jobs.

A small black ant with a glossy body, and the one most often in Sydney kitchens. It nests in wall cavities, the roof void and garden edges, trails along skirtings and cabling, and feeds readily on sweet bait.

Tiny and brown, with a distinct large-headed soldier. The sign is loose sand appearing between pavers, along the slab edge and in grout lines. Many nests to a colony, which is why we use oil-based granular baits.

Small, dull brown and fast-moving in thick trails. Nests hold many queens and connect with neighbouring nests, so infestations can stretch across several properties. Repellent sprays are especially counter-productive with this species.

These are the large night-active ants that nest in soil, hollow trees and timber that has softened with damp. Structural damage is uncommon in Australia, but a wall nest points to a leak worth chasing.

An Elite photo of ants emerging from mortar. The route runs through weep holes and cracked joints straight into the wall cavity, which is the usual home for a black house ant colony.

From an Elite job - gel bait set down on a live trail. The ants feed and carry it back to the nest, which is why we ask you not to wipe or spray that trail afterwards.
Where ants appear usually tells us where the nest is and which species we are dealing with.
A trail coming in from the external wall normally means a nest in the cavity or at the garden edge, and that entry point is where the tracing begins.
Fine soil pushed up along paving, driveways and slab joints is the classic sign of coastal brown ants nesting underneath.
Electrical fittings and switches stay warm, which is why ants nest in them. Do not spray into them; let us know and we will handle it properly.
Those spring and summer swarms of winged ants are mating flights. If they are coming out inside the house, there may be a mature colony in the building.
Bathroom trails around the shower, basin or toilet normally mean water: damp in the wall cavity, or a slow leak supplying the colony.
Bull ants and jumper ants nest in the lawn and garden beds. The sting is genuinely painful and in some people causes a serious allergic reaction.

A repellent does not kill a multi-queen colony, it divides it. A queen and several hundred workers shift to a new site, leaving you with two nests instead of one.
The difference matters. Retail sprays are repellent - ants sense them and avoid the treated area. Non-repellent products cannot be detected, so foragers cross them, pick up the active and take it back to the nest.
Bait is only taken if it matches what the colony wants right now. Their preference moves between sugar and protein as the brood changes, so we test and switch baits accordingly.
Results come over days as the bait spreads. Spray the trail the next morning and you have killed the ants that were carrying it home. Our blog explains budding in more detail.
Tracing first, then baits and non-repellent products that do the work after we leave.
We work out which ant it is and follow the trails back, which is what locates nests in wall cavities, under paving, along garden edges and in roof spaces.
Small amounts of sweet, protein and oil-based bait show what the colony is feeding on right now.
Indoor placements are gel on the trail - skirting, window frames, travel routes - sited away from children and pets.
We treat the foundation line, weep holes, door frames and paths with a non-repellent so incoming ants carry it with them.
Granular bait or direct treatment for coastal brown ant nests under pavers and in lawn edges.

The same bait does not suit every ant. This is how we choose.
| Species | Usually feeding on | Treatment approach | Common mistake |
|---|---|---|---|
| Black house ant | Mostly sweet liquids and honeydew, with protein demand during brood rearing | Gel bait along the trail, plus non-repellent treatment to weep holes and door frames | Daily detergent wiping of trails - it moves the foraging rather than stopping it |
| Coastal brown ant | Protein and oily foods | Oil-based granular bait over paving and lawn margins | Attacking a single visible nest while the rest of the colony's nests carry on |
| Argentine ant | Sugars primarily, sometimes protein | Slow-acting baits combined with non-repellent treatment across the boundary | A repellent barrier, which splits nests that hold many queens |
| Sugar ants (Camponotus) | Sweet foods and insects, mostly at night | Night-time trail inspection, bait near the nest, fix moisture in timber | Treating only in daylight when the ants are not active |
| Bull ants and jumper ants | Insects and nectar outdoors | Direct nest treatment in lawns and garden beds | Digging into the nest by hand and getting stung |
| Time of year | What is happening | What to watch for |
|---|---|---|
| Early spring (Sept to Oct) | The colony restarts and begins brood production, raising its protein needs | First trails inside, and sandy soil showing up in paving joints |
| Late spring to summer (Nov to Feb) | Foraging peaks, and warm humid spells trigger mating flights | Swarms of winged ants, and heavy trails following storms or heatwaves |
| Autumn (Mar to May) | The colony is at its largest and laying in stores before winter | Trails running into pantries and to pet food |
| Winter (Jun to Aug) | Quiet outside, but colonies in warm wall cavities keep working | Ants around the heater, the hot water unit and the kitchen |
Most failed ant treatments come down to what happens in the week after.
The garden is usually the source. Shrubs touching the walls, mulch up against the footings and irrigated beds give a colony everything it needs within a metre of your kitchen.
A storm is the most reliable trigger for an indoor ant problem. Nests in soil and paving flood, and the colony relocates somewhere dry, meaning your building.
A column of ants going in and out of a weep hole means they are nesting in the cavity, not the garden. Treating the garden bed in that case does nothing at all for a Pemulwuy home.
We follow the trail back to the colony rather than treating the spot where you noticed it.
Sweet, protein or oil-based baits chosen for the ant and the season.
Non-repellent products only - they are taken back to the nest rather than scattering it.
General ant treatments are covered. If ants come back within 6 months, so do we.

At roughly 26.8 km west of the city, Pemulwuy is on a route we run regularly. We cover it on scheduled runs, so a day's notice gets you the best slot. You will be given a time, not a window.
Terraces and semis share walls, roof voids and sub-floors, so ants move between houses without ever going outside. That is the single biggest factor here.
Terraces and semis that share walls, roof voids and drainage - so we look at what the property adjoins before deciding where product goes.
We do all of those. A good share of the Pemulwuy jobs we run are tenanted or strata properties, so the written record comes as standard.
Yes. Everything we use is registered for the purpose and applied at label rates, and we place product where people and animals do not go. Tell us about pets, aquariums or anyone with a respiratory condition at booking.
In most cases you can stay. Where an area does need to be left clear it is for a couple of hours at most, and we say so before we start.
Most ant control jobs in a Pemulwuy home take between one and two hours on site, depending on the size of the property and how much of it is affected.
Every general treatment carries a 6-month warranty. Call us if activity picks up again and we will arrange the return visit.
All of them. Pemulwuy sits alongside Prospect, Greystanes, Pendle Hill and Merrylands West in our coverage, and they are serviced on the same schedule.
